IMPROVEMENT IN GRAIN-BINDERS.

Specification forming part otl'mt-ters Patent No. 209,059, dated October I5, 1878; application tiled April 22, 1.878.

.To all whom it may concern:

Beit known that I, MosEs A. KELLER, of Fremont, in the county of Sandusky and State of Ollio, have invented certain new and useful Improvements in Grain-Binders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains-to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in automatic grain-binders; and consists in the arrangement and combination of parts that will be more fully describedhereinafter.

In the accoml'ianying drawings, which illustrate my invention, Figure 1 is a perspective view of my improved machine, taken from the rear. Fig. 2 is a perspective view of the i11- termittently-revolving gatherer and elevatingcylinder with one of the cam-'heads removed. Figs. 3, 4, 5, 6, and 7 are details of Fig. 2. Fig. 8 is a perspective view of a tapering flat or oval tooth, which may be employed in place of the round teeth. Fig. 9 is a sectional elevation, showing` the position of the teeth s s s when the bundle is being bound and the cylinder brought to a stand for the time being. Fig. 10 is also a sectional elevation, showing the position of the grain and teeth s s s during the operation of elevating a bundle and delivering another to the band and the compressing and binding mechanism. Fig. 11 is also a sectional elevation taken on the line o o of Fig. 15. Fig. I2 is a sectional elevation taken on the line t' t' of Fig. 15. Fig. 13 shows the cran kwheel n, showin g the pitman T, forming a lock to the cord-carrying arm M during the operation of the knot-tying mechanism forming the tie of the band, th en encircling the sheaf. Fig. 14 is a plan view of the mechanism and gearing giving the necessary power to the elevating and binding mechanisms. Fig. 15 is a full plan view of the whole machine. Fig. 16 is a detail view of the knottying mechanism 'that I at present am employing in full-sized machines, but not shown in present application, for full reference to that part of the machine can be obtained in my patentofFebruarylQ,1875,No.200,544. Thisview is simply added to aid in explaining the opthe end of the band material preparatory for the next bundle; also showing' the pinion 8, which transmits mot-ion to the tie-forming mechanism, and which is located in the tubular stationary shaft of the gathering-cylinder at a point suitable for that purpose. Fig. 18

is a longitudinal section taken through the center of the gathering elevating-cylinder and drive-wheel B, showing thefront or forward' part of the machine from the rear. Fig. 19 is a transverse section taken on the line y y of Fig. 15, showing the'cam-rack plate L3 that gives the necessary motion to the shaft 18, by which themotion is conducted to the tie-formin g mechanism. Figs. 20, 21, 22, and 26 are detail views of the automatic shitting mechanism for starting and stopping the gathering elevating-cylinder and binding mechanism. Figs. 23 and 24 are detail views of Fig. 19. Fig. 25 is a section of the drive-wheel.

Similar letters of reference denote corresponding parts wherever used.

My invention relates to certain improvements in that class of lmachines by which the grain is automatically picked up from the stubble in suitable bundles and securely bound by the operation of the machine.

Other features which I shall adopt in carrying my invention into effect will be understood f from the following description Referring to the drawings, A A represent a rectan guiar frame, which is mounted upon the axis of the driving-wheel B, and supporting wheel D by suitable brackets F, F1, and F2. C G represent the shafts by which the horse guides the machine, and E is the sea-t for the driver.

In the drawings, Fig. 25, Sheet 6, represents the drivin g-wheel, showing the springratchet dogs 15 and 16, which engage with a suitable ratchet-wheel, 14, which is rigidly secured to the shaft of said driving-wheel. The driving-wheel is loose on said shaft, and held up against the ratchet-wheel by a suitable collar, as shown in Fig. 1S; and to the inner end of the shaft is 'keyed the cog-wheel B', which gives motion to all the rest of the gearing, as

will be more fully described hereinafter It will be seen, by the arrangement of the ratchet-wheel above described, when the ma chine is backed all the gearing will stand still, making therefore safe from all danger of breaking or disarran gin g any part of the gear- 1n g.

When the machine is backed, and in moving the machine from field to field or on the road, the spring-ratchet dogs of said drive-wheel can be lifted out of gear, and thereby stop all the gearing. Vhen the machine moves forward, the cog wheel B1 meshes with cogwheels B2 and B3, and when the ratchet-dogs 15 and 16 are in gear with the ratchet-wheel 14, and the machine moves forward, the said Acog-wheels are in constant motion.

Cog-wheels B2 and B3 run loose on their respective shafts, the cog-wheel B2 being provided with a ratchet-wheel, 17, as seen in Fig. 22, Sheet 6. This ratchet-wheel engages with suitable ratchet-shiftin g dogs for starting and stopping the revolving gatherer, as more fully described hereinafter.

(log-wheel B3 is also provided with a ratchet on its hub, which ratchet engages with a suitable sliding clutch, 3, as shown in Fig. 14, Sheet 4. This gear gives the necessary movement to the binding mechanism, which will be fully explained further on.

In Fig. 2, Sheet 2, Fig. 14, Sheet 4, Fig. 15, Sheet 5, and Figs. 18 and 20, Sheet 6, A1 represents the stationaryl tubular shaft or axis upon which the intermittently-revolvin g gathererturns, and which extends longitudinally across the under side of the frame A A, and is fastened at the ends to the bracket F2 and main casting B4, which is secured to the bracket F1..

The gathering and elevating cylinder is one and the same mechanism, but performs a double function of collecting the bundle from the stubble and then elevating it to the point where it is being bound, and there stops until the next bundle is being elevated, and hence the name intermittent] y-revol ving gatherer. This gathering-cylinder is composed of two sections, L and L6, but moves as if they were but one cylinder, which is accomplished by means of the internal gear A4 and A5. (Represented in Figs. 15 and 17, Sheet 5, and Fig. 18, Sheet 6.) With these internal gear-heads mesh two corresponding pinions, 12 and 13, of equal number of teeth or cogs, and which are rigidly fastened to the ends. of a shaft which turns in a suitable bearing between the two pinions formed in the shuttle-seat A6, as represented in Fig. `1S, Sheet 6. This seat is rigidly secured to the tubular stationary shaft A1, and thus the said pinions have a perma- :ncnt location; and when motion is given to the inner section of the gathering-cylinder, it transmits motion to the outer section, thus causing the two sections of the gathering-cylinder to revolve simultaneously.

Instead of a tubular axis, as its equivalent a solid shaft may be used having a groove or grooves to admit a rod, shaft, or chain, for the purpose of transmitting the power to the tying mechanism. A shaft, rod, or chain, in connection with a specially-constructed tying mechanism, can 4be made to produce the desired results, and even a screw-shaft might be made to answer; but the tubular axis is tobe preferred.

The tubular shaft or axis gives greater rigidity and lightness, which are very important in a machine of this kind. The outer section cylinder, LG, has a sleeve, A7, to which is secured the internal' gear-head A5 and heads mi and mz, as represented in Fig. 18, Sheet 6. In the arms or spokes of these heads are pivoted the gleaner-teeth S, as shown in Fig. 2, Sheet 2. In the rims of these heads are lon g mortises of suitable size to receive the gleanerteeth S, and to allow them a slight vertical play as they spring up and down in said mortises while gliding over the undnlation of the ground, and upon the periphery of these heads is formed-a recess to receive the sheet-circles m. removed and the transverse bar p pushed round until it comes in the notch w, (shown in Fig. 6, Sheet 2,) when the said sheet-circle can be removed. It will be seen by this plan of construction that the cylinder is made entirely of metal, and therefore very durable, and can be made` very light-two very important .ob- `ects. J The other or inside section of the cylinder, L1, is constructed precisely on the saine plan, but the sleeve A2, to which are secured the internal gear-head A4, and head P3, extends on and up to the cog-wheel B2, at which end is securely fastened the driving-disk B, which comes' close up to the ratchet-wheel 17 of cogwheel B2, which is mounted on the tubular shaft A1, and runs loose on said shaft. 4

The disk B6 is provided with three dogs, fi, .and i2, Fig. 27, which are pivoted at one end to said disk, on that side next to the ratchetwheel 17, and overhang s the teeth 4of said.

ratchet-wheel. These three dogs have each a` round pin, u, projecting through the disk by means of a suitable slot formed in said disk .for that purpose, and these pins u project into the camway of the cam-lever J, which ispivoted upon the` hub of said disk, and close upV to the face of said disk, for the purpose of receiving the projecting pin a of the dogs. 0n the opposite side of the disk, while the gathering-cylinder is motionless, the pins u ot' the dogs i, fil, and i2 stand in the camwayA Y In taking off these circles the screw t is t lever J has reached again its vertical position, and is prevented from going any farther by the stop-staple J the disk B6 continues to revolve until the pin u of the dog, then in gear with wheel 17, has reached the highest position in the camway of lever J, at which point the 'dog is disengaged from the ratchet-wheel 17. The elevating-cylinder then stops, having completed one-third of a revolution, and is held in that position by the automatic stop L4. (shown in Figfl, Sheet 1, Figs. l and 19, Sheet 6, and Fig'. 14. Sheet 4,) which drops into the concave end of one of the projecting lugs l ZI Z2 of disk B6.

At each end of the elevating-cylinder are stationary cam-heads L and L2, head L2 being fastened on the tubular shaft A1, and the head lL to a short sleeve, A3, which sleeve is fastened in the eye of casting m3. (Shown in Fig. 15, Sheet 5.) These heads have camways formed in them, as shown in Fig. 5, Sheet 2, in which move the rollers y upon the cranked ends of the rods y. These rods are made square, and pass through similarly-shaped openings in the hinges or heads of the gleaner-teeth S, so that when the rod turns the teeth will turn wit-h it. By this manner of connecting the gleaner-teeth and the camheads together l control the action of the gleaner -teeth S to elevate the points of said teeth.

When the cylinder is set in motion to elevate a bundle, the teeth are prevented from drawing into the ground, and are caused to quickly descend to the ground to gather the next bundle, so that there will be no space left unraked during the operation of elevating.

a bundle.

Having thus described the construction of the elevating mechanism, I will now proceed .to describe the construction of the binding mechanism.

The rod h3 is pivoted to a short lever, h2, and slides on a pin in the slot 26. (Shown in Figs. 11 and l2, Sheet 4.) The lever h2 is rigidly secured to the end of the shaft d2, which is mounted in suitable bearings on the rear sill of frame A A. To this shaft are also securely fastened the levers d and d, to which are pivoted at their upper ends the supportin g-iin gers l5" and P2 by links cz. To lever di is also pivoted the spring-latch It. 4The supportingtingers P and P2 are secured to a shaft, G, and lingerPl is pivoted on the shaft G. Now when the e'ndV of rod h3 comes in contact v with one ofthe rollers or projections o3 of disk Fig. 9 of Sheet 3;) This pawl 9 catches on the under side of the hook-proj ection of the springlatch, an d lifts thelatch from the shaft at the moment the binding-arms begin to recede and relieve their hold upon the bound bundle, and the weight of the bundle will carry down and back the supporting fingers, as indicated-by the dotted line fr, Fig. l0, and the bound bundle will thereby drop squarely on the ground. The supporting-fingers will then re-` main in that position until the elevating-cylinder is again starled to elevate the next bundle, when they will again be brought forward, and thus they act automatically uponbundle after bundle.

The cog-wheel B3 runs loose on its shaft, and is in constant motion during the operation of the machine. At the inner end of the shaft that is next to the elevatiu g-cyliuder is keyed the crank-wheel n, with the roller c pivoted on the end of the shaft, as shown, and on the other end of said shaft is keyed t-he crank A. Upon this shaft is mounted the shifting-clutch 3, that fastens the cog-wheel B3 to` the shaft during the operation of bindin ga bundle. This clutch is prevented from turning upon the shaft by a spline, and has a project-ing pin, as shown in Fig. 14, Sheet4. This pin, in combination with the crank-lever 4, performs the functions of startingvand stopping the binding mechanism. To the crank-wheel n is pivoted the pitman T, with the slotted end, the other end ot' the pitman being pivoted to the curved arm Tl. This arm is keyed tothe shaft G, and to said shaft is secured the band-carrying arm M and segment-gear b. The shaft Gis pivoted in a suit-` able bearing, b h, at the end next to the curved arm T1, and in another bearing in thestandard 3l. upper end of this standard is pivoted, upon a stationary stud, the compressor-arm N, with its segment-gear c meshing in gear with segment b. The segment-gear a is provided with a rubber spring, h, which rests on the compressor-arm N, and the compressor-arm is extended back to form an arm for the cord-spool O. Now, when the elevating-cylinder has all .but completed thc elevating of a bundle, one

of the projections fvf of disk B' comes in collision with the angular lever 4 at that end next tovsaid disk, and thereby lifts the opposite end of said lever from the pin of the clutch 3, when the clutch will be pushedin gear with the cog-wheel B3 by the spring Z, Y

as represented in Fig. 14, Sheet 4, and the shaft, with said clutch, crank-wheel n, and crank A8, all begin to rotate with said cogwheel B3. The pitman T will then cause the binding-arm M to descend, encircling the bundle with the band, and, by means of the segment-gears a and b, the compressor-arm N moves upward, compressing the bundle, while the spool O is drawn backward, thereby taking up all the slack of the band around the bundle. When the pitman T has come in contact with the roller c', thel band-carryin g arm M has reached its extreme downward point,

(Shown in Fig. 9, Sheet 3.) To the l' when it will remain there stationary until the heel end T3 of pitman T has passed down and oil the roller c', as shown in Fig. 9 of Sheet 3. During the time the said pitman was passing over the roller c the roller on crank A has acted on the straight portion ofthe rack-cam plate L3, and has produced a double stroke to said rack-cam in the following manner: At the moment the roller of' crank A comes in collision with that portion and end of cam represented by b a Fig. 24, Sheet 6, it causes the rack-plate to move downward until the roller cornes in collision with the spring-switch Z A, which is precisely when the crank A8 passes over its dead-center, and as the crank continues on it will cause, by the action of the roller upon the spring-switch, the said rackplate to travel in the opposite direction until the roller has passed oi' the spring-switch; and when the roller has passed into the extreme end of the cam the sliding clutch 3 is drawn out of gear by the action ot' its projecting pin, before described, coming in collision with the hooked end of angular lever 4, which is so constructed as to produce this result. At the moment the clutch 3 is drawn out of gear with cog-wheel B, the shaft stops, and is securely held dead by the automatic stop 7, (shown in both Figs. 12 and 14, Sheet 4, and Fig. 15, Sheet 5,) which drops into the notch formed in the outer periphery ot' the crank-wheel n. At this point the band-carrying arm M has reached its highest position and the compressor-arm its lowest position, the bandearrying arm M stretching the cord again across the circle the elevating-teeth assume when they elevate a bundle, thus preparing the band for the next bundle. The end of the cord or band material has been irmly secured in the knotting mechanism K, which mechanism has received its working motion by means of the rack-cam plate L3 during the movement ofV said rack-cam above described, and has transmitted the power to the knotting mechanisln in the following manner: The rack portion ot' cam-plate L3 gears into a corresponding pinion, g, as shown in Fig. 19, Sheet (i. Close up to this pinion, on the same shaft, is a roller, a y, for guiding the rack so as to move free and easy in mesh with pinion g. This pinion is rigid upon the shaft 18. (Represented in Fig. 18, Sheet 6.) Said shaft has secured to its inner end a spur-pinion, 8, and

from this pinion the power is communicated to the knot-ty in g mechanism, similar to the one patented by me February I9, 1878, No. 200,544 but I do not limit my machine or invention t0 employing this special knotting mechanism, as any other suitable binding mechanism can be employed that it may be seen tit and proper to employ.

It will be seen by reference to the drawing, Fig. 17, Sheet 5, an opening is made in the stationary tubular shaft Al, allowing the wheel 10 to mesh with pinion 8; but other mechantcal appliances could be admitted at this openmy improved machine, the operation is as follows When the horse is` guided along the buttend ot' the swath or unbound bundles, as thev` case may be, the drive-wheel B is almost in line with the horse, while the supporting-wheel D strides the swath, thus leaving the gleanerteeth S S S S to gather up the cut grain. When a bundle of sucient size, in the judg mentot'the driver, has accumulated in the gathering-teeth, he with his foot pushes the lever H forward, thereby starting the elevating-cylinder, which will divide the bundle from the swath by the aid of the yielding fenders f f f j', and elevate it to the height in line parallel with the cylinder, as represented in the drawing, Fig. 9, Sheet 3, when the cylinder is automatically thrown out of gear, as before described: In the meantime anotherrow of gatherin g-teeth has reached the ground to commence gathering the next bundle. When the cylinder is again started, it elevates the first bundle over the top of the cylinder, pushing the cord or band along back, drawing it from the spoolOuntil the bundle has lodged in the supporting-fingers P, P1, and P2. At this moment the cylinder again stops, and immediately the cordcarrying arm M begins to descend, carrying the cord over and around the bundle and down through the opening into the casing K of the knotting mechanism. In the meantime the compressor N has also ascended, pressin g the bundle against the binding-arm M, and at the same time the spool O has been Adrawn backward,and, by means of its tension g, the slack of the band around the bundle is all taken up. The ends of the band are then firmly united into a hard loop-knot, in the manner described in my patent of February 19, 1878, No. 200,544. During the operation of uniting the ends of the band the end of the cord that constitutes the band for the next bundle is firmly secured and held in the knotting mechanism (also shown and described in the above patent;) but a section of that portion of the lknotting mechanism is represented in Fig. 16, Sheet 5.A The knot is completed, the end of the cord again secured as above stated, the binding and compressor arms begin to recede, lifting the spring-latch R from the shaft Gr', when the weight of the bound bundle will carry down and back the supporting-fingers P, P1, and P2, and the said bundle will drop squarely on the ground, without any danger of falling on one of its ends, as would be the case without these fingers.

The location of the driver's seat over or nearly over the driving-wheel and the location of binding-arms on the rear sill of the frame of the machine, having been made thc subject of a separate application, are disclaimed in this application. y
